So there’s VSCode (aka. Visual Studio Code) and there’s Visual Studio 2019. If you’re developing an ASP.NET Core MVC application using Visual Studio 2019, when you’re running the application in debug mode, if you modify one of your cshtml views, your application that’s running in the browser automatically picks…(Read More)


I was working with some ASP.NET WebApi code and needed to test something using the Swagger UI. Usually, it’s just a matter of starting the project and going to your /swagger directory. Unfortunately, in this case, I went to my swagger URL and got an error saying “Failed to load API definition — Fetch…(Read More)


Seems like there’s a lot of action(s) happening over on GitHub.  How do I get a piece of that action(s)?  Wheee!  Puns!  (I’ve been cooped up in my house too long.) So if you’re a .NET Core developer or an ASP.NET…(Read More)


[TL/DR? – skip to the bottom] I ran into a problem with an ASP.NET MVC Core app today and it took me a while to figure it out. Here’s the problem: on an extremely simple and straightforward form, I couldn’t get a field in my model to POST back to the server…(Read More)

If you’ve followed this blog for a while, you know that I’m obsessed with being able to deploy Entity Framework Core (EF Core) migrations from published (“dotnet publish”) DLLs instead of from the project code.  Why?  Because if you care about DevOps-y things like automated deployments — especially in Visual Studio Team Services…(Read More)


I’ve been neck deep in Azure App Authentication (aka. Easy Auth) lately trying to get it to work with ASP.NET Core applications.  I wrote a bunch of labs/walk-throughs last week to demonstrate how to make it work.  Here are the posts in the Azure Easy Auth series: Lab 1, Lab 2…(Read More)
